Problems solved by technology

However, while the traditional microstrip line-type power distribution network has the above-mentioned advantages, in the case of a large number of distribution ports and a high frequency band, the consistency of each port is poor, and the mutual coupling effect between adjacent ports is strong and even affects each port. The problem of amplitude and phase characteristics between

Embodiment Construction

[0030] For ease of understanding, the feed network structure of the microstrip array receiving antenna of the 3D traffic management radar system is taken as an example here, and the specific implementation structure and work flow of the present invention are described as follows in conjunction with the accompanying drawings:

[0031] The feeding network of the microstrip array receiving antenna of the above-mentioned 3D traffic management radar system is a microstrip line power distribution network, and the specific composition and connection structure of the antenna are as follows:

[0032] refer to figure 1 , the microstrip line power distribution network includes two groups of power distribution sub-networks divided into six channels, four groups of Wilkinson power dividers 40 with phase shifters 30 and four phase-shifted microstrip line segments 50 . Among them: the branch ports of the two groups of power distribution sub-networks divided into six channels face each other,...

Abstract

The invention belongs to the technical field of antenna feed, and particularly relates to a compact type microstrip line power distribution network. The network comprises a first power distribution subnetwork and a second power distribution subnetwork, wherein each of the first power distribution subnetwork and the second power distribution subnetwork is divided into six paths. The first power distribution subnetwork is connected with the second power distribution subnetwork through Wilkinson power dividers with phase shifters. Other branch ports of the first power distribution subnetwork and other branch ports of the second power distribution subnetwork are connected with phase shift microstrip line segments. Eight coaxial feed probes are correspondingly arranged on ends of four phase shift microstrip line segments and on the total ports of the four groups of the Wilkinson power dividers, vertically penetrate through a medium plate and then are connected to a metal group place. The network is advantaged by compact size, small amplitude of each port and small phase position error, and an antenna applying the power distribution network can be allowed to have good performance of high pointing accuracy and low minor lobe.

Description

technical field [0001] The invention belongs to the technical field of antenna feeding, and in particular relates to a compact microstrip line power distribution network. Background technique [0002] In mobile communication, satellite communication, wireless sensor network nodes and wearable wireless devices, it is necessary to reduce the size of the device or accommodate more functional modules in a limited space, so the miniaturization of array antennas is an inevitable trend of development, and power distribution The network is an essential and important part of the array antenna. In view of this, the traditional microstrip power distribution network with convenient processing, small size, light weight, moderate bandwidth and easy integration is widely used. However, while the traditional microstrip line-type power distribution network has the above-mentioned advantages, in the case of a large number of distribution ports and a high frequency band, the consistency of ea...
